Title: Improvements in method of diminishing the tension in the joint between welded piecesof metal with different dilatation
IPC: B23K31/02
Filed: 1920-10-22
Abstract: 178,479. Rustan, G. Oct. 22, 1920. Cased or compound forms.-In making a composite article consisting of a metal casing welded to a core of a metal having a different co-efficient of expansion the core is formed, prior to welding, with radial slots extending from its outer surface, so that on heating or hardening the article subsequent to w.elding, the tension in the joint is reduced and cracking of the article prevented. After welding, the slots may be opened up to the centre of the core or to the central axial opening therethrough. The casing may be of hard metal such as tool steel and the core of a cheaper metal such as cast or welding steel.

Abstract: 448,083. Well packers. O'CONNOR, D. L. T., 1104, Medical Arts Building, Hot Springs, Arkansas, U.S.A. Oct. 31, 1935, No. 30094. Addition to 428,014. [Class 85] The well packer of the parent Specification is modified by the provision of means whereby when the packer is collapsed, the valve is maintained in an open position. As shown, the slips 28 and casing- engaging springs 24 are carried by a shell 23 connected to a sleeve 22 slidably fitted over the valve block 7. When the packer 32 is contracted, the sleeve 22 engages pins 35 carried by the valve 10 to hold the latter open. In another form, downward projections on the sleeve engage the pins 35 to hold the valve open and may be moved laterally to clear the pins to permit the valve to shut. In a further form, lugs extend upward from the valve to engage the sleeve. Below the valve is an apertured block 12 with an edge 16 for scraping deposits from the casing and a web 17 for deflecting the scrapings. In a modification, the scraping edge is formed by resilient knives secured to the block.

Abstract: 1,241,694. Photographic exposure meters. SANGAMO WESTON Ltd. June 24, 1969 [June 25, 1968], No.30307/68. Heading G2A. A photographic exposure meter 10 has an associated attachment 14 comprising a photosensitive device 15 which is capable of being electrically coupled to the meter 10 via contacts 17, 19 and 18, 20 so that an electric measuring instrument 12 within the meter may be energized in accordance with the degree of illumination of photo-sensitive device 15. The attachment is secured to the exposure meter by a bayonet type coupling formed by contacts 17, 18 and is arranged wholly to exclude light from a photo-sensitive device 11 within the exposure meter. The front wall of the casing of the attachment has an exposure calculator mechanism. In the preferred circuit arrangement shown, a three position switch 23 enables completion of a circuit including measuring instrument 12 either through photoresistor 15, an intermediate position which provides an off position or through a fixed resistance R c  which serves for checking the voltage of a mercury battery 16. The application of an attachment serves to shunt R 1  across photo-cell 11 and instrument 12 and brings R 2  into series circuit with the attachment.

[Class 117.] Glass rods, tubes, &c. are sorted according to their thickness by passing them singly to the outer periphery of one or a series of rotating drums having grading slots adapted to select articles up to a maximum size, the selected articles passing to the inside of the drums and being discharged by shoots. The apparatus described comprises three sorting drums arranged in series, and each provided with a double row of apertures. As shown in Fig. 3, the effective width of the apertures is adjusted by blocks 40, and the selected rods are discharged by the laterally directed shoots 18, Fig. 2, supported inside the drums. The rejected rods are supported by the blocks 40, their ends lying in grooves between blocks 41, 42, and are carried round under guard-plates 43, 44 for delivery to the next drum in the series. At the delivery point, the rods are discharged by an internal sprocket wheel 53 rotated by engagement of its teeth with the drum apertures. The rods are fed to the upper drum by a toothed wheel 33 which carries them singly from a hopper 11 under a guard-plate 39. A spring 49 controls the delivery of the rods to the drum, and spring-controlled blocks 51 press each gently into the sorting apertures. A pivoted stop 32 is used to withdraw the mass of rods from the feeder when desired. All the sorting drums and the feed sprocket are geared to rotate in synchronism.
